FUEL-HEATER.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed December 24, 1917. Serial No. 208,650.

To all whom it may concern:

Be it known that I, GEORGE H. HAYES, a citizen of the United States, residing at Hazelton, in the county of Barber and State of Kansas, have invented a certain new and useful Improvement in F uel-Heaters, of which the following is a specification.

My invention relates to improvements in fuel heaters. It is particularly Well adapted for heating fuel for an explosive engine, so that the engine may be quickly started in cold weather.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing Which illustrates the preferred formof my invention,

Figure 1 is a side elevation of an ordinary intake manifold and carbureter provided with my improvement.

Fig. 2 is a vertical sectional view on the' line 2-2 of Fig. 1.

Fig. 3 is an enlargedv view of the heating receptacle and parts connected therewith.

Fig. 4 is a vertical sectional view on the line 4 -4 of Fig. 3.

Similar reference characters designate similar parts in the different views.

1 designates an ordinary carbureter which discharges into an intake manifold of the ordinary type, and designated by 2.

3 designates a liquid fuel conductor having a branch 4 connected to and discharging into the carbureter, and provided with a branch which forms a bypass which discharges into the manifold 2, and which comprises a pipe 5 having a shut off valve 6, a receptacle 7 having a vertical partition 8. which divides the receptacle into a closed compartment 9 and an open top compartment 10, and a conductor 11 which dis charges into the manifold 2 and which has a screw threaded end fitted in a threaded outlet hole in the top of the compartment 9. The pipe 5 has a screw threaded end which is fitted in a threaded inlet hole in the bottom of the compartment 9.

For supporting the receptacle 7 and for conveying heat to the compartment 9, there is provided supporting means consisting of a plate 12 of heat conducting material, such as steel or iron, the upper end of which is secured to the body 13 of the engine by a bolt 14. The lower portion of the plate 12 has a hole through which the conductor 11' extends, the latter being provided with a peripheral flange 15 which clamps the plate 12 to the top of the compartment 9.

In the operation of my invention, the valve 6 is opened to permit oil, such as gasolene, or coal oil, to flow by gravity from a supply tank, not shown, through the pipes 3 and 5 into the compartment 9. The valve 6 may then be closed. Liquid fuel, such as coal oil or gasolene is then poured into the compartment 10 and ignited. The compartment 10 may be provided above its bottom with one or more air inlet holes 16 to assist in combustion of the fuel in said compartment. The compartment 10 is under and adjacent to the manifold 2, so that heat from the fuel burning in the compartment 10 will heat the manifold. The plate 12 is disposed adjacent to the open top of the compartment 10 so as to be heated thereby, thus conveying heat to the manifold 2 and compartment 9, as well as serving its function of supporting and bracing the receptacle 7.

The engine may be readily started with the heated fuel passing from the compartment 9 through the conductor 11 into the manifold. After the engine has been started running, it will take its supply of fuel mixed with air from the carbureter 1 in the ordinary manner.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is 1. In a fuel heater for explosive engines, an intake manifold, a receptacle having two compartments, each adapted to contain liquid fuel, one compartment being closed to the atmosphere, the other compartment having an open top disposed so as to heat said manifold, the closed compartment being disposed so as to be heated by fuel burning in the open compartment, a conductor into Which the closed compartment discharges and which discharges into said manifold, and a valved supply pipe discharging into said closed compartment,

2. In a fuel heater for explosive engines, an intake manifold, a receptacle having two compartments adapted to contain liquid fuel, one being closed to the atmosphere, the other having an open top below and adjacent to said manifold, supportin means for said receptacle located so as to "be heated "by fuel burning in said open compartment, means for supplying the closed compartmentavith liquid fuel, and a conductor into Which the closed compartment discharges and which discharges into said manifold.

'3. In a fuel heater for explosive engines, an intake manifold, a .rece ptacle for liquid fuel having two compartments disposed side by side, a one being closed to the atmosphere and the other having an open top located below and adjac'entto the manifold means for supplying the closed compartment with liquid fuel, a conduotorintowhich the closed compartment discharges and which discharges .into .said manifold, and a heat conducting supporting member heldclampe d :to

said receptacle by :said conductor, 7 and i disposed so as to be heated by fuel burning in said open compartment. i

4. In a fuel heater for explosive engines, an intake manifold, a carburetor discharging therein, .a liquid. duel condu cter discharging into the carbureter and having a by-pass discharging into said manifold and including a receptacle having tWo compartments adapted to contain liquid fuel,-0ne .beinga .closed compartment forming a passage for liquid passing through said by-pass, the other compartmentbeing open to the. atmosphere, a shutoff valve inisaid bypass, and a supporting-heat conducting plate ,held clamped to said receptacle by a portion of lthe logy pass and .disposediso as to be heated zhy fuel burning in said open compartment.

In testimony WlClGl'BOfI have signed my name .to this specification.
